Definitions

  • the technology of the disclosure relates to wired and/or wireless communication systems employing a Radio-over-Fiber (RoF) communication system.
  • RoF Radio-over-Fiber
  • Wireless communication is rapidly growing, with ever-increasing demands for highspeed mobile data communication.
  • so-called “wireless fidelity” or “WiFi” systems and wireless local area networks (WLANs) are being deployed in many different types of areas (e.g., coffee shops, airports, libraries, etc.).
  • Wireless communication systems communicate with wireless devices called “clients,” which must reside within the wireless range or “cell coverage area” in order to communicate with an access point device.
  • Picocells are radio-frequency (RF) coverage areas. Picocells can have a radius in the range from a few meters up to twenty meters as an example. Combining a number of access point devices creates an array of picocells that cover an area called a "picocellular coverage area.” Because the picocell covers a small area, there are typically only a few users (clients) per picocell. This allows for simultaneous high coverage quality and high data rates for the wireless system users, while minimizing the amount of RF bandwidth shared among the wireless system users.
  • One advantage of picocells is the ability to wirelessly communicate with remotely located communication devices within the picocellular coverage area.
  • RoF wireless system utilizes RF signals sent over optical fibers.
  • Such systems include a head-end station optically coupled to a plurality of remote units.
  • the remote units each include transponders that are coupled to the head-end station via an optical fiber link.
  • the transponders in the remote units are transparent to the RF signals.
  • the remote units simply convert incoming optical signals from the optical fiber link to electrical signals via optical-to-electrical (O/E) converters, which are then passed to the transponders.
  • the transponders convert the electrical signals to electromagnetic signals via antennas coupled to the transponders in the remote units.
  • the antennas also receive electromagnetic signals (i.e., electromagnetic radiation) from clients in the cell coverage area and convert the electromagnetic signals to electrical signals (i.e., electrical signals in wire).
  • the remote units then convert the electrical signals to optical signals via electrical-to-optical (E/O) converters.
  • the optical signals are then sent to the head-end station via the optical fiber link.
  • Wired and wireless peer-to-peer analog and digital communications are generally limited in range and coverage, respectively. Enhancing the range of wired peer-to-peer connections may require complicated amplifying and/or repeating requirements. Extending the coverage of wireless peer-to-peer connections typically requires a denser antenna deployment and/or transmitted power increase, which may be limited by government regulations, wireless standards, and battery peak power and energy storage considerations. In addition, extending the coverage may be prohibited by the use of proprietary protocols, such as medical equipment.

Glasfaserbasiertes drahtloses Kommunikationssystem nach Anspruch 1, wobei die Zellenkopfeinheit darüber hinaus eine Videoübertragungseinheit umfasst, die dazu ausgelegt ist, ein an der Zellenkopfeinheit eingegangenes Videosignal auf mehrere Geräte über mehrere Glasfaserkabel aufzuteilen, die mindestens eine Glasfaser umfassen.
  12. Glasfaserbasiertes drahtloses Kommunikationssystem nach den Ansprüchen 1 bis 11, wobei mindestens eine der mehreren abgesetzten Zugriffseinheiten darüber hinaus einen Funkfrequenzeingang/-ausgang, einen DC-Eingang/Ausgang und/oder einen optischen Eingang/Ausgang umfasst.
  13. Verfahren zum Ermöglichen einer Kommunikation zwischen einem ersten gleichrangigen Gerät in einem erste Versorgungsbereich und einem zweiten gleichrangigen Gerät in einem zweiten, anderen Versorgungsbereich, Folgendes umfassend:
    optisches Verbinden mehrerer abgesetzter Zugriffsstellen (30) mit einer Zellenkopfeinheit (20) über mehrere Glasfaserkabel (32), wovon jedes mindestens eine Glasfaser umfasst und dazu ausgelegt ist, ein Funk-über-Faser-Signal von der Zellenkopfeinheit an die mehreren abgesetzten Zugriffsstellen (30) zu übertragen;
    Bilden eines ersten Versorgungsbereichs, der einer ersten der mehreren abgesetzten Zugriffsstellen zugeordnet ist;
    Bilden eines zweiten Versorgungsbereichs, der einer zweiten der mehreren abgesetzten Zugriffsstellen zugeordnet ist und sich vom ersten Versorgungsbereich unterscheidet;
    dynamisches Herstellen, und zwar über eine Optoschalterleiste (212), einer Funk-über-Faser-basierten optischen Verbindung über mindestens eines der mehreren Glasfaserkabel, um das erste gleichrangige Gerät mit dem zweiten gleichrangigen Gerät zumindest teilweise über die Funk-über-Faser-basierte optische Verbindung kommunizieren zu lassen; und
    wobei die erste der mehreren abgesetzten Zugriffsstellen drahtlos mit dem ersten gleichrangigen Gerät kommuniziert und die zweite der mehreren abgesetzten Zugriffsstellen drahtlos mit dem zweiten gleichrangigen Gerät kommuniziert.
  14. Verfahren nach Anspruch 13, darüber hinaus umfassend, eine Aufforderung zum Herstellen von Kommunikationsverbindungen zwischen dem ersten gleichrangigen Gerät und dem zweiten gleichrangigen Gerät vom ersten gleichrangigen Gerät oder zweiten gleichrangigen Gerät zu empfangen.
  15. Verfahren nach Anspruch 13, darüber hinaus umfassend, eine Aufforderung zum Herstellen von Kommunikations-verbindungen zwischen dem ersten gleichrangigen Gerät und dem zweiten gleichrangigen Gerät von einem anderen als dem ersten und zweiten gleichrangigen Gerät zu empfangen.
